If a diesel won't start it generally is due to one or all of three things
fuel not getting to the cylinders
air not getting to the cylinders
not enough compression

smoke usually means unburned fuel, but not white smoke. White smoke usually means water in the cylinders. This could be a head gasket leak.

First check cranking speed. Is the battery charged and strong enough to crank the engine fast enough. Otherwise you are not getting enough compression for it to fire.

If cranking speed is up and compression ok check your air and fuel filters to make sure they aren't clogged.

Check to see if you have water in the fuel. Water makes diesel fuel look milky.

If you have glow plugs make sure they are working. Cold weather always causes hard starts but glow plugs help.

If you still have the problem then you need to have a diesel tech run some tests.
